00:10	herdrick	tomoj: according to this: http://github.com/technomancy/leiningen/blob/master/sample.project.clj
00:10	herdrick	you add :jvm-opts "-Xmx1g"
00:10	herdrick	to your defproject
00:11	herdrick	(well, with whatever value you want after -Xmx of course
00:11	herdrick	)
00:12	herdrick	though I'm not getting any satisfaction from it.
00:12	herdrick	maybe this is some Incanter issue
00:12	herdrick	because even with the default heap size there should be plenty of room
00:12	aedon	Does anyone here use emacs viper-mode to edit clojure? I can't get it to automatically switch to viper-mode when I edit clojure files.
00:13	herdrick	i'm only got a 3 by 1000 incanter matrix
00:13	herdrick	of Doubles
00:13	herdrick	so, what, 25k of data
00:14	herdrick	and multiplying it by it's transpose is what blows with the OutOfMemoryError
00:14	herdrick	(mmult (trans three-by-1000) three-by-1000)
00:14	herdrick	looks like liebke: isn't here
00:18	tomoj	isn't the jvm started by the lein shell script?
00:18	hiredman	it is
00:18	tomoj	so how could project.clj affect the jvm opts used?
00:19	hiredman	you can also just set JVM_OPTS or JAVA_OPTS or whatever
00:19	tomoj	unless the shell script parses it.. which would be weird
00:19	herdrick	hiredman: ok, thanks
00:19	hiredman	a) it totally could
00:19	hiredman	b) lein used to launch a new jvm
00:19	hiredman	c) I don't think it ever does now
00:20	tomoj	so :jvm-opts is useless, right?
00:20	hiredman	no idea
00:20	hiredman	^-
00:25	technomancy	no, it's not useless
00:25	technomancy	it's actively harmful
00:25	technomancy	wtf.
00:26	technomancy	I took it as a patch from someone, and they were like, OK; thanks for applying this
00:26	technomancy	but I never tried it for myself.
00:35	mudge	hello
00:35	mudge	newbie question
00:35	mudge	I have a Java application loading up a clojure program that I wrote, but when the Java application tries to load my clojure program, this error comes up: Could not locate clojure/core__init.class or clojure/core.clj on classpath:
00:35	mudge	at clojure.lang.RT.<clinit>(RT.java:295)
00:36	technomancy	tomoj: lein does fork a subprocess for the project's JVM, but I'm not sure if the CLI options are fixed at that point.
00:38	mudge	anyone know what I should do?
00:41	hiredman	mudge: make sure clojure/core.clj is on the classpath
00:44	mudge	what's the difference between a class loader and a classpath?
00:49	technomancy	mudge: a classloader is a Java mechanism to load class files from disk or another source into memory; a classpath is the locations that are searched for those files.
00:49	mudge	technomancy: awesome, thanks
01:05	technomancy	if someone's having problems AOT-compiling namespaces in a certain order, it means they're leaving out calls to require, right?
01:08	technomancy	wow... interesting that this Clojure course in India is being offered for free.
10:50	ev4l	anyone here had trouble installing swank-clojure via ELPA?
10:58	Bahman	ev4l: Compilation errors are fine.
11:05	ev4l	Bahman: right, but it seems the package isn't marked as installed after opening the package list after an emacs restart =/
11:06	Bahman	ev4l: I had the same issue...
11:06	Bahman	and it was because I marked more than one package to install.
11:06	Bahman	Just did it one package at a time and it went all well.
11:07	Bahman	Hope it helps.
11:10	ev4l	Bahman: thx!
11:11	Bahman	ev4l: Did you managed to install it?
11:13	kodis	How do I access a static method from a local class? I imagine this is a simple thing to do, but can't make it work.
11:14	ev4l	Bahman: It seems that when i mark swank-clojure for installation it tries to re-install deps like clojure mode (that's already installed)
11:14	raek	kodis: local?
11:14	Bahman	ev4l: Ah, yes! That's a headache.
11:14	raek	static methods are use like this: (Class/method args...)
11:14	Bahman	I deleted .emacs.d/ and started afresh.
11:14	ev4l	Bahman: will attempt a cleanup
11:15	Bahman	Just mark the package you do want...it will calculate the deps but can't re-install them.
11:15	kodis	raek: Just a simple java class file in my current working directory.
11:15	raek	you have to either import the class or use it's full name
11:15	raek	what classpath did you start clojure with?
11:16	raek	or, how did you start clojure?
11:17	kodis	raek: with a -cp of '.', and still no joy: only 'No such namespace:' or java.lang.ClassNotFoundException:
11:17	kodis	clojure was started with 'java -cp . -jar /usr/share/java/clojure.jar'
11:18	raek	classes in the default package is handled specially by the JVM, but I don't know of that's the issue here
11:19	raek	if you type the name of the class in the repl, you get a ClassNotFoundException?
11:21	raek	also, is the class compiled?
11:21	kodis	With a class of 'J' containing a static method of 'j', '(J/j)' throws 'java.lang.Exception: No such namespace: J', while '(J)' throws 'java.lang.Exception: Unable to resolve symbol: J in this context'
11:22	raek	have you compiled the .java file into a .class file?
11:22	raek	clojure can only use compiled classes
11:23	kodis	Yes, both J.java and the resulting J.class are in my current working directory.
11:23	raek	ok
11:23	raek	can you make a folder named, say, "foo" and put the .class file in there
11:24	raek	then try enetering "foo.J" into the repl
11:25	kodis	user=> foo.J
11:25	kodis	java.lang.ClassNotFoundException: foo.J (NO_SOURCE_FILE:0)
11:25	raek	hrm, maybe the -jat options throws away the -cp args
11:26	raek	try "java -cp '.:/usr/share/java/clojure.jar' clojure.main"
11:26	raek	(use semicolon instead of a colon if you are on windows)
11:26	raek	*the -jar option
11:27	kodis	Well, at least that produces a different error:
11:27	kodis	user=> foo.J
11:27	kodis	java.lang.NoClassDefFoundError: foo/J (wrong name: J) (NO_SOURCE_FILE:0)
11:28	raek	ah, try adding "package foo;" in the .java file
11:28	raek	now the class is in the foo package
11:29	raek	(the directry structure has to match)
11:29	raek	if this works, you could try to revert all the "foo" stuff
11:29	raek	it was probably just the classpath that was the problem
11:31	kodis	Progress! foo/J still throws an exception, but an import now works!
11:32	raek	and typing foo.J returns foo.J?
11:32	raek	if so, clojure can at least find the class
11:33	kodis	Solved! foo.J returns foo.J, and (J/j) evals to 42 as expected. Thanks for walking me through this.
11:34	kodis	I'm surprised that it's not a bit more straight forward. It seems that classes can't be imported, only packages. Can that be correct?
11:35	raek	"importing" is just a matter of not having to type the full name of the class
11:36	raek	so, after running (import 'java.util.contrib.BlockingQueue), one can use the name BlockingQueue
11:36	raek	instead of having to type java.util.contrib.BlockingQueue every time
11:37	raek	I think it should work to have the class file in the root directory, remove the package line from the .java file and use the class under the name J
11:37	raek	since "J" would be its full name then
11:38	raek	but classes in the "default package" (those without a package prefix) are handled specially by the JVM
11:38	raek	i'm not aware of the details, just that "usage of the default package is discouraged"
11:39	kodis	Raek: Yes, that's what I thought, but I still don't see how to access a class without a package.
11:39	raek	wait a sec, and I'll try something
11:40	kodis	Yes, I can see how failing to work would provide some discouragement!
11:41	raek	"You can’t use classes in the default package from a named package."
11:41	raek	right.
11:42	raek	here's the issue on StackOverflow: http://stackoverflow.com/questions/283816/how-to-access-java-classes-in-the-default-package
11:42	kodis	Ah, okay -- unfortunate, but at least now I can stop trying to get that to work and just put the code in a proper package to begin with.
11:44	raek	yes, putting everything in a directory named as the project will do
11:47	kodis	raek, you mean 'in a project named...', right? Just moving the class file into the foo directory doesn't seem sufficient.
11:48	raek	i meant that if your project is called, say, myproj all files (including the .clj files) should be in myproj/
11:49	raek	java classes has to be declared to be in the package using the "package xx.yy.zz;" statement
11:49	aedon	kodis: there's really no magic here. if you have a directory named 'x' and you put that dir in the classpath, then files in the default package should go in x, files in the foo package should go in x/foo and files in the foo.bar.baz package should go in x/foo/bar/baz
11:50	raek	clojure files should have namespace declarations reflecting the directory structure: (ns myproj.main)
11:51	raek	if you have a file with the path myproj/main.clj
11:52	raek	http://clojure.org/libs
11:55	kodis	Right, so the usual java name mappings are still in effect. It still seems that the 'package foo;' line is required though -- just a bare Class won't do.
11:57	raek	yes, the package declaration must match the directory structure too
11:57	raek	you could say that clojure namespaces and java packages are the same thing
11:57	raek	at least when considering the classpath
11:58	kodis	Yup. Organizing classes into packages seems like it's the best practice anyway.
12:00	kodis	It's a bit surprising that I can't directly access a simple, unpackaged class, but I guess I understand the rational.
13:16	LauJensen	Good morning (UGT) :)
14:07	cais2002	good night every one
16:04	cmcclell	quick question
16:05	cmcclell	What is the best syntax highlighting offered in emacs23/linux? clojure-mode only seems to highlight known fns. User defined macros/fns do not get highlighted at all
16:08	LauJensen	cmcclell: Most, if not all, use Clojure-mode, but you can add something like idle-highlight (IIRC the name correctly) if you want more highlighting
16:08	LauJensen	technomancy should have the details :)
16:09	cmcclell	thanks. For some reason, aquamacs + clojure-mode seems to do more (like highlight macros, even user defined ones, in green). Not sure why ubuntu + emacs23 seems to do less
16:11	hiredman	it depends on the color scheme you use, and if you are using console emacs, your TERM
16:13	LauJensen	There are actually 2 colors themes out there, by etate whos a Clojurian.
16:23	arohner	what's the best way to tell which dependency causes lein to download an artifact?
16:23	arohner	lein pom && mvn dependency:tree appears to be lying to me
16:29	arohner	ah. It appears lein exclusions aren't transitive
16:33	neotyk	Hi, is it possible to compile java with new lein?
16:34	arohner	neotyk: I haven't tried this, but it might be useful: http://github.com/antoniogarrote/lein-javac
16:34	raek	there is this, but I haven't tried it myself: http://github.com/antoniogarrote/lein-javac
16:34	raek	whoa
16:34	neotyk	I have tried it :(
16:36	neotyk	lein doesn't find compile-java
16:40	the-kenny	Why isn't clojure.contrib.graph/lazy-walk checking if n is in the set of nodes? I just experienced some very strange behaviour when passing a node not in the nodes-set.
16:48	technomancy	cmcclell: I can't remember ever making clojure-mode highlight user-defined macros.
16:48	technomancy	neotyk: did you add lein-javac as a :dev-dependency instead of a regular dependency?
16:48	technomancy	and run "lein deps" after adding it?
16:48	neotyk	technomancy: yes
16:49	neotyk	both
16:49	technomancy	neotyk: hmm; possibly a bug in the plugin then; I haven't used it myself.
16:49	neotyk	technomancy: not true, didn't run lein deps
16:49	technomancy	aha
16:52	neotyk	technomancy: now it compiles
16:52	technomancy	cools
16:52	neotyk	is there a hook to make compile-java be executed with compile?
16:53	technomancy	neotyk: hooks are a pretty new feature; I don't know if lein-javac has been updated to use them yet.
16:54	neotyk	I want to update it, but don't know how to use a hook
16:56	technomancy	neotyk: you would need to add robert-hooke as a dependency to lein-javac and add a leiningen.hooks.javac namespace that calls add-hook to wrap #'leiningen.compile/compile
16:56	technomancy	more details here: http://github.com/technomancy/robert-hooke
16:56	technomancy	if you have trouble go ahead and ask on the leiningen mailing list; I'm taking off for a while.
16:56	neotyk	technomancy: great, will give it a try, thanks
16:56	arohner	is there any metadata on an AOT classfile that identifies which version it was compiled with?
16:57	arohner	I've got that stupid java.lang.NoSuchMethodError: clojure.lang.RestFn.(I)V error, and I want to make it easier to identify
17:56	thunk	Compojure noob question: When I reevaluate a defroutes form, jetty doesn't serve the modified form. How do I get the repl development cycle going with compojure?
18:02	thunk	nm, stuarth set me straight.
18:14	itistoday	what is the purpose of :as in destructuring?
18:14	itistoday	here's an example from The Joy of Clojure: (loop [[part & parts :as work] work]
18:15	itistoday	if they already have 'work'.... why are they doing :as work?
18:16	hiredman	itistoday: what is the point of a loop?
18:17	hiredman	if you rewrote the loop as a function, how would it look?
18:17	itistoday	one sec... let me take a screenshot
18:17	hiredman	…
18:17	hiredman	why?
18:17	clojurebot	why not?
18:17	itistoday	or are you already answering my question
18:17	hiredman	clojurebot: buzz off
18:18	clojurebot	No entiendo
18:18	hiredman	itistoday: I am asking you a question
18:18	itistoday	hiredman: it's sometimes hard to tell with you :-p
18:18	hiredman	itistoday: what is the purpose of loop?
18:18	itistoday	to provide a point to jump back into for recur?
18:19	hiredman	so when writing binding forms for a loop you have to keep in mind the recur
18:20	hiredman	if you don't rebind work in the loop's binding form it will always be bound to value it had outside of the loop
18:21	itistoday	hiredman: oh ok, i see, i thought that wouldn't happen, that work would be bound to the modified version...
18:21	hiredman	(fn [{part & parts :as work}] ...)
18:21	hiredman	why would it?
18:21	itistoday	no, rather: (fn [{part & parts] work] .. )
18:21	hiredman	er
18:21	hiredman	nope
18:22	hiredman	(fn [[part & parts :as work]] ...)
18:22	itistoday	(ok, messed up on the closing bracket)
18:22	itistoday	oh ok
18:22	itistoday	i see, you're redefning loop as a function
18:22	hiredman	15:25 < hiredman> if you rewrote the loop as a function, how would it look?
18:23	itistoday	heh
18:23	itistoday	ok well i'm still shaky on all the syntax
18:23	itistoday	it hasn't become second nature yet
18:23	hiredman	the point is parameter names are rebound to new values for each call
18:23	hiredman	just like loop bindings are rebound for each iteration
18:24	itistoday	ok, i see, it's because the 'work' on the right is only "listened to" once
18:24	itistoday	on the first call
18:24	itistoday	from then on it's as if it wasn't there and loop were a function definition
18:24	hiredman	more or less
18:24	mudge	hello
18:25	hiredman	the binding form at the top of a loop is for establishing the initial bindings for the first iteration
18:25	itistoday	right
18:25	mudge	I am using :methods in the gen-class function, how do I specify a method signature that returns void?
18:25	itistoday	it should stick this time hopefully :-p thanks hiredman
18:26	itistoday	mudge: i've seen other people ask that question, and i think the answer was don't worry about it
18:26	itistoday	mudge: (i could be wrong, but just try it and see if it works)
18:27	mudge	itistoday: thanks, what am I supposed to try?
18:28	itistoday	mudge: i don't know. :-) I thought you might. :-p
18:28	technomancy	mudge: just return nil
18:28	mudge	can't put nil inside :methods
18:28	mudge	I just tried this: :methods [[appleFun [] void]]
18:28	mudge	and that worked
18:29	mudge	so using void as the return type in :methods worked
18:29	technomancy	any other JoC reviewers here? I think I was missed on the latest review round email.
18:30	itistoday	technomancy: you mean the link to the latest copy?
18:30	mudge	this is pretty sweet, I'm using a class generated with clojure inside my java code
18:30	technomancy	itistoday: I have it; I'm just wondering when the reviews are supposed to be in.
18:31	itistoday	technomancy: ah, yeah i'm probably not a reviewer then cause i don't know what you're talking about :-p
18:32	itistoday	technomancy: happen to have any guess on when the next chapter's going to be out?
18:32	itistoday	i'm wondering whether i'll get to it before it comes out or not...
18:33	technomancy	itistoday: I think the final review rounds were 3 or 4 weeks ago, but I don't know beyond that.
18:34	itistoday	k
18:39	mudge	is JoC pretty good?
18:42	technomancy	it's very good.
18:42	technomancy	but not terribly introductory.
18:42	itistoday	how does the lazy-seq macro work?
18:43	itistoday	i don't get this: (list 'new 'clojure.lang.LazySeq (list* '^{:once true} fn* [] body))
18:43	itistoday	err, i should be more specific
18:43	itistoday	i don't get: '^{:once true}
18:43	hiredman	don't worry about it
18:43	itistoday	hehe
18:44	itistoday	,'^{:once true}
18:44	clojurebot	EOF while reading
18:44	technomancy	it's a hint to the compiler that the function's body should be cached and not re-run.
18:44	hiredman	the implementation is not something you need to worry about
18:44	technomancy	pretty low-level obscure stuff.
18:44	hiredman	you just want to know what ^ is?
18:44	itistoday	hiredman: i know i don't need to.
18:45	itistoday	yeah
18:45	itistoday	and what's the deal with the quote
18:45	itistoday	i read that as: "don't evaluate something"
18:45	hiredman	itistoday: http://clojure.org/reader
18:46	itistoday	ok, so "don't evaluate some metadata"?
18:46	itistoday	(i'm guessing that in 1.2 ^{} is #^{})
18:46	technomancy	the quote is a no-op there as far as I can tell
18:46	technomancy	since the thing that's quoted is a literal anyway
18:46	technomancy	itistoday: yes
18:47	hiredman	technomancy: well, it quotes the fn form
18:47	technomancy	hiredman: ooooh... the reader passes the quote on... interesting.
18:48	hiredman	right
18:48	hiredman	quote is a reader macro
18:48	technomancy	that's almost an operator precedence issue
18:48	hiredman	the reader only deals with transforming it to a s-exp
18:48	hiredman	it is
18:48	itistoday	ok, so it's not quoting the metadata
18:48	itistoday	but what follows it?
18:49	hiredman	right
18:49	itistoday	i see
18:49	hiredman	the reader attaches that metadata to the symbol fn*
18:49	hiredman	and then you get (quote fn*)
18:49	itistoday	so my understanding of this thing has gone from completely opaque to the transparency of those glass blocks people put as walls in their bathrooms
18:50	itistoday	thanks though, i'll save it for another day
18:50	itistoday	it's just a really weird way of doing laziness
18:50	itistoday	*lazyness
18:50	itistoday	(i think)
18:50	itistoday	streams in scheme are understandable to me, this is still magic :-p
18:51	hiredman	not reallyy
18:51	hiredman	it jsut generates a thunk
18:51	hiredman	and the thunk generates the first part of the lazy-seq
18:51	hiredman	the next part has it's own thunk
18:52	hiredman	etc etc
18:57	itistoday	ok, i might understand it now after looking at LazySeq.java, at least it's become a bit more clear
18:58	itistoday	btw, is it inefficient to setup try/catch blocks in java?
18:58	itistoday	i know that's a java question, not a clojure question... but they're currently closely tied together so maybe someone here knows the answer
18:58	itistoday	i just see them all over the place and i thought they were inefficient
19:03	itistoday	ooo, looks like this is the answer: http://stackoverflow.com/questions/141560/should-try-catch-go-inside-or-outside-a-loop
19:03	itistoday	seems like they're really cheap, ... err.. don't affect performance at all unless something goes wrong
19:08	itistoday	i really have to thank rich for getting rid of that # in 1.2's syntax.
19:26	itistoday	what is that part of speech where a word represents a larger whole?
19:27	itistoday	like America representing the government or something?
19:28	itistoday	#languagearts was empty :-p
19:33	bortreb	Synecdoche -- like saying "the pen of the president" to refer to his power or some law that was made
19:37	itistoday	bortreb: thanks! you know that word was bouncing around in my head, i should've looked it up, something's obviously wrong with me. :-p
19:39	itistoday	i'm glad i finally got to use that word: "The Government" is also not an individual entity with a single consciousness that's out to get you. It's a synecdoche that refers to a large group of _elected_ officials. If there's something wrong, the entire country shares the blame.
19:54	bortreb	yep Synecdoche drives our computers crazy... it's so hard to figure out what it refers to in NLP.
19:56	itistoday	bortreb: cool!
19:57	itistoday	bortreb: anything i can google that you're working on?
19:58	thunk	Unrelatedly: "Synecdoche, New York" was an amazing movie
20:10	bortreb	isittoday: http://groups.csail.mit.edu/genesis/
20:12	bortreb	, (+ 1 2)
20:12	clojurebot	3
20:20	itistoday	bortreb: cool, thanks for the link! looking at the video now
20:24	itistoday	bortreb: have you looked at jmonkeyengine? java3d is really out of date
20:26	itistoday	bortreb: (admittedly that probably doesn't matter for your purposes :-p)
20:32	bortreb	I'm actually working on porting Jake2 to clojure so we can use that environment as a hime for the AIs
20:39	itistoday	bortreb: why not use jME?
20:41	bortreb	never heard of it?
20:42	bortreb	itistoday: have you used it for stuff in the past? is it awesome?
20:42	itistoday	bortreb: yes. it is awesome, and actively being developed, and has a large community.
20:43	itistoday	bortreb: it's really the best 3d java engine that i know of
20:44	itistoday	bortreb: and unlike jake2, it's not outdated. ;-)
20:48	bortreb	itistoday: that's really cool. I looked at goldsrc but I wanted to go with something simple that I could use with java. I missed jmonkeyengine
20:50	bortreb	itistoday: know any clojure related projects using this / a good starting point?
20:50	itistoday	bortreb: google the two
20:51	itistoday	bortreb: i personally don't, but google showed some stuff
20:51	itistoday	bortreb: like this: http://nakkaya.com/2010/05/25/jmonkeyengine-hello-world-in-clojure/
21:00	itistoday	technomancy\|away: why? http://paste.pocoo.org/show/233242/
21:28	technomancy	itistoday: sounds like the plugin may not be designed to work with that leiningen version
21:28	technomancy	ping dnolen; he wrote it
21:29	itistoday	technomancy: thanks, how do i ping him?
21:29	itistoday	you mean contact him when he's online?
21:29	itistoday	(using the rc2 btw of lein)
21:35	dabd	is it possible launch a standalone swank server (i.e., one that is not
21:35	dabd	associated to a leiningen project) and connect to it with
21:35	dabd	slime-connect?
21:36	itistoday	technomancy: now lein won't uberjar: http://paste.pocoo.org/show/233244/
21:36	itistoday	technomancy: and it deletes everything in the lib/ folder
21:37	thunk	dabd: (swank/start-repl)
21:37	thunk	w/ optional port argument
21:38	dabd	thunk: swank/start-repl is a clojure function right?
21:40	thunk	dabd: Correct. swank-clojure has to be on your classpath, and you have to (use :swank) or equivalent.
21:42	mudge	I noticed that when clojure.jar is not on the class path, this error occurs: java.lang.NoClassDefFoundError: clojure/lang/IFn
21:42	dabd	my current setup does not allow me to start a repl from emacs. I can start a swank server with 'lein swank' and then slime-connect from emacs.
21:43	mudge	I have a problem where I have an application written in Java that uses a class compiled from clojure that give an error that clojure core is not on the classpath
21:43	mudge	it seems to recognize that clojure.jar is on the classpath though
21:44	mudge	it seems to recognize clojure code, just not stuff that uses clojure core
21:45	hiredman	do you have clojure.jar on the classpath?
21:45	mudge	yes, i think it is because it is not giving me this error which occurs when clojure.jar is not on the classpath: java.lang.NoClassDefFoundError: clojure/lang/IFn
21:46	mudge	so i think clojure.jar is on the classpath, and is being recognized by java
21:46	hiredman	why not just look at the classpath?
21:46	hiredman	what is on the classpath?
21:48	mudge	I can't see it for sure because my clojure code is loaded by an external Java application that I don't have access to
21:53	hiredman	mudge: if you don't know, then you can't fix
21:55	mudge	but I do know I am changing the classpath and I am pretty sure that clojure.jar is on the classpath
21:55	mudge	because I can change the configuration so that the java.lang.NoClassDefFoundError: clojure/lang/IFn error occurs
21:55	mudge	and then add in clojure.jar and that error goes away
21:56	mudge	and instead I get a clojare core error, that clojure core cannot be found on the classpath
21:56	mudge	so, is it possible that clojure.jar can be on the classpath without clojure core being on the classpath?
21:57	mudge	clojure core is in clojure.jar so it doesn't make sense to me
21:57	mudge	does clojure have its own class loader?
22:02	mudge	this is the exact error I'm getting: java.io.FileNotFoundException: Could not locate clojure/core__init.class or clojure/core.clj on classpath
22:02	mudge	clojure.jar is on the classpath though
22:04	mudge	i'm thinking that my problem is similar to the problem here: http://stackoverflow.com/questions/2352242/how-can-i-embed-clojure-in-an-rcp-application
22:15	mudge	anyone seen this error: Could not locate clojure/core__init.class or clojure/core.clj on classpath
22:15	mudge	clojure.jar is in the classpath
22:17	itistoday	mudge: how are you running and what are you running?
22:20	mudge	I generate java classes from my clojure source code, which is one file, and put it in a jar. Then my jar and clojure.jar are sent to an external java application that tries to run my clojure code and spits out that error
22:20	mudge	my clojure program is a 3rd party module for an existing java program that uses java webstart
22:21	itistoday	mudge: you mean it tries to load them at runtime?
22:22	mudge	yes
22:22	itistoday	mudge: ah, well, i have zero experience with that, sorry, can't help :-\
22:23	mudge	okay, thanks for your willingness
22:24	itistoday	np
22:33	bortreb	mudge: in the worst case, you might consider unjaring all the clojure files from clojure.jar and repackaging them in your own jar
23:32	unlink	Are macros vogue for designing event-driven API libraries?
23:33	unlink	(defhandler client (event-one [x y z] blah) (event-two [] ...))
23:53	Bahman	Hi all!
